Answers
Given info : KOFl electronics bought a shipment of TVs at a net price of $477.36 each.
To find : after discounts of 15% , 10% and 4%, the list price of TV is ..
solution : if net price of an object is R and successive discounts are p % , q and r % then list price is given by = R/(1 - p/100)(1 - q/100)(1 - r/100)
so, list price of TV = 477.36/{(1 - 15/100)(1 - 10/100)(1 - 4/100)}
= 477.36/{(1 - 3/20)(1 - 1/10)(1 - 1/25)}
= 477.36/{17/20 × 9/10 × 24/25}
= 477.36 × 20 × 10 × 25/(17 × 9 × 24)
= 650
Therefore the list price of TV is $ 650.
